The New Museum is on an inner-kid-friendly roll this year, first with worms and now with a slide. A 102-foot-long plastic tube, to be precise, connecting the fourth floor of the SANAA-designed museum to the second. Visitors can do more than touch the Carsten Höller artwork-they can suit up in helmets and pads and take the three-story slide for spin.

Höller has previously put slides in art centers across the globe (Berlin, Milan, São Paolo) including a 2006 installation that turned the Tate Modern into a "playground overrun with visitors shooting through five tubular slides like... packages going through pneumatic tubes."
